You use Hitachi Device Manager (HDvM) to manage your VSP and HUS storage systems. Within the HDvM GUI, in which two locations would you perform storage allocation tasks? (Choose two.)

A. Resources

B. Administration

C. Logical Groups

D. Tasks

Which two statements regarding the Hitachi Dynamic Link Manager Least I/O and Least Block algorithms are true? (Choose two.)

A. The Least I/O and Least Block algorithms redirect the I/Os to a single path determined by the algorithms.

B. The Least I/O and Least Block algorithms redirect the I/Os to a pair of paths determined by the algorithms.

C. The Extended Least I/O and Extended Least Block algorithms distribute sequential I/Os to a set of paths and random I/Os to another set of paths.

D. The Extended Least I/O and Extended Least Block algorithms distribute I/Os to paths depending on whether the I/O involves sequential or random access.
